Anecdotally, I'd noticed that tea vs. coffee seems to be generational. My wife and I drink tea at home while our parents prefer coffee (what coffee we have in the house is pretty much just for guests and some recipes that require it). Likewise, our siblings and their SOs seem to favor tea. My grandparents also tended to favor tea.
It sort of feels like a generational flip-flop thing to me between tea and coffee.
